英文: Abstract: In order to solve the double parameters enveloped in the geartooth flank generating,the complicated double parameter envelope is simplified to the generating process between work-piece and imaginary crown generating gear by means of mathematical
中文: 文摘:为了解决直接求解展成法加工中存在的复杂双参数包络问题时的困难,提出通过数学变换,将此包络问题转化为假想平面产形轮与工件之间的展成问题来进行研究.推导了假想产形面的方程和各阶偏导矢,于是可获得产形面的微分几何参数.通过分析假想平面产形轮与工件之间的展成运动,即可得到被展成齿面上任意指定点的全部一至三阶微分几何参数.
